Application filed'necember 19, 1914. Serial No. 878,163.

To all whom it may concern I Be it known that I, V,ERI\ON BOYLE, acitizen of. the United States, and resident of Paterson, in the countyof Passaic'and State of New Jersey, have invented a new and usefulImprovement in Circular Looms, of which the following'is aspecification.

My invention relates to circular looms and more particularly to theweaving pin support for use in connection with such looms.

The object is to provide a support capable of being vertically andlaterally adjusted and fitted to receive weaving pins either tubular orsolid and of varying diameters and with these ends in view, my inventionconsists in certain features of construction and combinations of partsas willbe' hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of a weavingpin and parts of the central column of a circular loom intimatelyassociated therewith, 'Fig. 2 is a vertical. section ofthe same in theplane of the line A-A, Fig. 1, Fig. 3 is a detail elevation showingtherack and pinion for raising and lowering the weaving pin support andhence the weaving pin, Fig. l is an enlarged top plan detail showing themeans for holding'the pin support against rotation and for securing thepin removably to its support, Fig. 5 isa transverse section in the planeof the line BB, Fig. 2, showing the worm and worm wheel for operating.the aforesaid raising and lowering pinion, the worm shaft being shown insection with operating handle removed, and Fig. 6 is a vertical sectionin detail showing the means for securing a weaving pin of lesserdiameter to the pin support.

- The pin support is here shown as tubular and is denoted by 1. Theweaving pin is also shown as tubular and is denoted by 2 in Figs. 1, 2and 4, and by 2* in Fig. 6. The central hollow column of theloom inwhich the weaving pin support .1 is located. is made up of a tubularstep piece 3, and the superposed hubs and hub extensions of 100melements which form no part of my present invention except'in so far asthey form a housing for the weaving pin support. The support 1, togetherwith the weaving pin 2 carried thereby, is raised and lowered by meansof a rack 4 on its side, in the present instance at its lower portion,which rack is engaged by a pinion 5 on a shaft 6 journaled transverselyin the base 7 of the central column and. operated by a worm wheelsecured on the shaft 6 engaged by a worm 8 on a shaft 9, the latteroperated by any suitable and well known means, for example, a crank, notshown. To hold the support 1 against a rotary motion, it is providedwith laterally projecting lugs 10, 11, at its upper end,'here shown asdiametrically disposed and fitted to enter pockets 12,

13, in a ring piece H fixed in the central I column of the loom,

The weaving pin 2 shown in Figs. 1, 2 and 4, has a diameter equal tothat'of the support 1 and is the largest size feasible to use in mypresent structure. Its lower end fits within the upper end of thesupport 1 and a laterally projecting narrow flange 15,.

(see Fig.4-);-rests onthe inner portionsof the upper ends of the lugslO, 11. Screws I 16, 17", are tapped into the upper ends ofthe lugs 10,11, in such position that their heads overlap the flange 15 and lockthepin 2 .to the support 1. To enable the pin to beremoved without removingthe screws, the

flange. 15 is mutilated by providing it at intervals with recesses 18,(see Figl i) which,

when the screws 16, 17, are loosened and the pin 2 rotated to bring-arecess 18 intofregister with a screw'head, permit the pin to-be liftedout and replaced at pleasure. To determine the point at which theweaving shall take place about the pin 2, a ring 19 is provided, theupper end of which embraces the pin with a sliding fitand" forms ashoulder 20 in immediate proximity to the surface'of the pin. Theweaving point ring 19 is car I ried by a base ring 21 through the wallsof which adjustingv screws 22 pass and impinge against the outer wall ofthe ring 19! The base ring 21' is in turn seated in a fixed step 23through bosses 24: 25,0f which there are horizontal bores 26, 27, andcounter bores 28, 29, in the latter of which screws 30,-31, withcone-shaped inner ends are engaged. Thesaid cone-shaped inner ends coactwith the inclined outer ends of plungers 32, 33, in the bores 26, 27, toadjust the base ring 21. The weaving point'ring and the base ring withtheir means of adjustment serve to center the weaving pin with respectto the vertical axis of the loom with great precis on.

.When it is desired to employ a weaving pin of less diameter than themaximum, I employ what I am pleased to call an adapter for securing theweaving pin to the pin support, and the weaving point ring is alsomodified to suit the diameter of the weaving pin. The latter, however,requires only the inward extension of the annular shoulder, as shown at34, Fig. 6.

The adapter consists of a plate 35with a central upwardly extending hub36 in which the weaving pin 2* is secured. in a manner in which the pm 21squite similar to that secured to its support as has been hereinaboveexplained, and a downwardly extending annular portion 37 provided with anarrow lateral flange corresponding to the flange 15 on the pins 2 andfitted to be secured in the upper end. of the support 1 in the samemanner as the pin 2, is fitted and secured.

While I have shown the weaving pins hollow or tubular, it is obviousthat they might be solid if so desired and secured to the support oradapter-in the same manner as the tubular pins are secured. In practiceoneadapter may be used for several sizes of weaving pins by simplymaking the bases of the weavingpins fit the adapter as herein shown.

It will be noted that the weaving pins may be removed and exchanged atpleasure through thetop of the column and that the pin supportmay alsobe lifted out by and its basering, and that the-projection of theweaving pin upwardly through the Weaving less to suit "the desiredretarding friction of the-woven tube between theshoulder 20 and the endof'the weaving pin.

It will also be noted thatthe adapter and'weaving pin 2 areinterchangeable in the structure shown in F ig'. l, theassemblage ofparts shown in Fig. 6 being introduced simply to show the modificationof the weaving point ring when the adapter is used.

What I claim is: V 1. In a circular loom, a weaving pin, a weaving pointring surrounding the weaving pin, a tubular support for the pin andmeans for adjusting the said support and hence the pin relatively to thering.

2. In a circular loom, a weaving P a weaving point ring surrounding thepin, a
